Features of evaluating properties of field emitters using effective parameters

The paper considers the features of evaluating the effective parameters of nanostructured field cathodes - the area of the field emission S eff and the field gain \beta_{eff}. A variety of approaches to parameter estimates is shown. The dependence of these estimates on the magnitude of the applied e...

Summary:The paper considers the features of evaluating the effective parameters of nanostructured field cathodes - the area of the field emission S eff and the field gain \beta_{eff}. A variety of approaches to parameter estimates is shown. The dependence of these estimates on the magnitude of the applied electric voltage is shown by the example of a three-dimensional model of a carbon nanotube. The possibility of the experimentally estimation of individual emission sites using a computerized field projector is considered. A method for analyzing the current-voltage characteristics in Fowler-Nordheim coordinates (IVC-FN) with an interval estimate of the effective parameters is proposed.
